The shooting happened just before 3:30 p.m. Wednesday in the 14800 block of Empire Street in Woodbrdige. Prince William County Police officials tell ABC 7 that it appears that the boy wandered into an unlocked relative's pickup truck parked in front of a home, found a loaded handgun, fired it and accidentally shot himself.

The boy was taken to a local hospital, where he was pronounced dead. Authorities identified the deceased as Kyrell Kyyon McNeill.

"I was getting ready to pull my garbage can back in to the house and I heard pop," neighbor Timothy Frye, who heard the shooting, said.

Police said the shooting appears self-inflicted and accidental. They have not released whose care the boy was under.
